| 英文摘要 | the molar heat capacities of the azeotropic system (0.30 mol water + 0.70 mol cyclohexane) were measured by an adiabatic calorimeter in temperature range of 78-320 k. the functions of the heat capacity with respect to thermodynamic temperature were established. the phase transition took place in temperature ranges of 184-190, 271-276 and 276-283 k corresponding to the solid-solid phase transition of cyclohexane, solid-liquid phase transition of water and solid-liquid phase transition of cyclohexane, respectively. the corresponding enthalpies and entropies of the phase transition were found to be 4.559 kj mol(-1), 24.510 +/- 0.065 j k-1 mol(-1); 2.576 kj mol(-1), 9.454 +/- 0.041 j k-1 mol(-1); and 2.040 kj mol(-1), 7.296 +/- 0.029 j k-1 mol(-1), respectively. the thermodynamic functions and the excess thermodynamic functions of the azeotrope were derived based on the relationships of the thermodynamic functions.
